|About the stats|
So far in his career, Ian Happ has made 2,438 plate appearances and pitched 1 innings. Happ has been worth 11.0 Wins Above Replacement (10.9 as a hitter and 0.0 as a pitcher) and 3.1 Wins Above Average (3.0 as a hitter and 0.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 11.0 WAR becomes 12.1 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the 3.1 WAA becomes 4.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Happ 19.3 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Ian Happ has a Hall Rating of 18, meaning he would not be in the Hall of Stats if his career ended today.
